16 | 17 | ## Introduction 18 | 19 | This Discord bot integrates with LeetCode to provide daily challenges, random problems, user information, and more. It uses `discord.js` to interact with the Discord API and `leetcode-query` to fetch data from LeetCode. 20 | 21 | --- 22 | 23 | ## ✨ Features 24 | 25 | - Daily LeetCode Challenge notification 26 | - Delivers a random LeetCode problem based on difficulty 27 | - Fetches user profile information 28 | - Displays user streak information 29 | - Provides a user-friendly help command 30 | 31 | --- 32 | 33 | ## 📒 Commands 34 | The bot does not use the traditional message command approach; instead, it uses a slash command approach. This means that when you type `/`, you will see a list of available commands in the guild. The commands provided by this bot are: 35 | - `/potd` - Shows the LeetCode Daily Challenge 36 | - `/random ` - Shows a random LeetCode problem 37 | - `/user ` - Shows User Info 38 | - `/streak ` - Shows user Streak Info 39 | - `/help` - Shows help message 40 | - `/topic` - Shows a list of LeetCode topics to choose from 41 | 42 | --- 43 | 44 | ## ⚙️ Installation 45 | 46 | 1. 📂 Clone the repository: 47 | 48 | ```bash 49 | git clone https://github.com/your-github-username/leetcode-discord-bot.git 50 | ``` 51 | 52 | 2. 📂 Navigate to the project directory: 53 | 54 | ```bash 55 | cd DDoL 56 | ``` 57 | 58 | 3. 🛠 Install the dependencies: 59 | 60 | ```bash 61 | npm install 62 | ``` 63 | 64 | 4. 🔐 Create a `.env` file in the root directory and add your Discord bot token and channel ID: 65 | 66 | ```plaintext 67 | TOKEN=your-discord-bot-token 68 | CHANNEL_ID=your-channel-id 69 | DEVELOPER_ID=your-discord-id 70 | ``` 71 | 72 | --- 73 | 74 | ## 🛠️ How to Set Up a Bot on Discord 75 | 76 | 1. Create a new application 77 | Go to the [Discord Developer Portal](https://discord.com/developers/applications?new_application=true) and create a new application. 78 | 79 | 2. Configure `OAuth2` 🔑 80 | 81 | 3. In your app's settings, navigate to OAuth2. 82 | - Open the OAuth2 URL Generator and select the bot option. 83 | - Under Bot Permissions, select Administrator. 84 | - Set up the bot 85 | 86 | 4. Go to the `Bot` section and enable the following gateway intents: 87 | - `Server Members Intent` 88 | - `Message Content Intent` 89 | - Get your bot's `TOKEN` 🔐 and Create a Discord server 90 | 91 | 5. Create a new server in Discord and retrieve the `Channel ID` where your bot will operate. 92 | 93 | --- 94 | 95 | ## 🚀 Usage 96 | 97 | 1. Start the bot 🤖: 98 | 99 | ```bash 100 | npm run start 101 | ``` 102 | 103 | 2. Invite the bot to your Discord server using the OAuth2 URL generated from the Discord Developer Portal. 104 | 105 | 3. Use the commands in any channel the bot has access to. 106 | 4. Register slash commands in your guild using `;register guild `. Please don't provide the server ID if you want to register commands in your current guild. 107 | 5. If you want to register slash commands in all guilds, ignore the 4th step and run `;register global` 108 | --- 109 | 110 | ## ✨ Contributing 111 | 112 | Contributions are welcome!
